Small rodents can cause big problems for a food business, whether it’s a full-service restaurant or a corner store. Aside from scaring off customers, rodents spread bacteria at an alarming rate — on their bodies, in their droppings and through their urine and saliva.
Rodents urinate and defecate frequently as they move about, so it doesn’t take them long to spread dangerous microorganisms from one end of your business to the other.
Rodent infestation without effective pest control measures in place is one of the most common crucial infractions found by Health Inspectors across the country. Crucial infractions are health violations that present a high risk to public health — and they often come with a hefty fine.
Whether you’re the owner, manager or Food Handler in the business, it’s extremely important to implement effective pest control and monitoring procedures in your restaurant. Training your employees to identify and react appropriately to signs of a rodent infestation is an essential part of any pest control management system. The CIFS Food Handler Certification Course covers pest control and maintaining food premises and equipment to prevent pests from entering your business.
The more employees you train, the more ground you’ll cover in the business, and the less likely it is that a few little mice will become a mighty problem. Everyone has a part to play in the fight against rodent infestation.
Sure, they’re cute, but don’t be fooled by their cuddly exterior — rodents are a big deal if they get into your commercial kitchen. In no particular order (and by no means an exhaustive list):
Don’t forget that rats and mice also hurt your bottom line. A customer who sees a mouse or rat in your restaurant won’t be returning but they will tell their family and friends about what they saw, and they might post a negative online review about your business (or even share an embarrassing photo of it on social media).
There are two keys to preventing rodent infestations:
Rodents tend to use the same routes and entryways into buildings; check your building for holes or cracks in walls or floors and seal them up. Keep in mind that a rat can enter a building through a one-inch hole and a mouse can enter through a hole about the size of a dime.
Doors and windows are easy entry points for pests, so make sure that yours are tight-fitting and kept closed (when not in use). We recommend installing:
Food deliveries are another point of entry for rodents. Always use suppliers with a good reputation and verify that they have a pest management plan. When deliveries arrive, check for signs of rodent infestation before signing off. Check the packaging for bite marks, holes or tears and look inside the truck for signs that pests are or have been there.
You have the right to conduct a thorough inspection of the delivery vehicle and goods. Failure to do so can result in costly problems for your business, so if you see any signs of rodent infestation, reject the entire delivery and inform your supplier.
Blocking the rodents' access to food is accomplished through effective waste disposal and storage, as well as good overall sanitation. If you have a dumpster on your property, move it as far away from the building as possible and never leave waste or unused food lying around. Be sure to:
You should monitor your food business regularly for signs of pests — at least once every two weeks. Remember to check storage areas and hard-to-reach areas, like underneath equipment and under shelves. Use a flashlight to help you see more clearly.
Look for any of the following signs of rodents:
If you see a rodent or any signs that there are rodents in the building, the odds are slim that it's the only one. You'll need to act quickly to avoid a full-blown infestation (if you don't have one already).
If you detect rodents in your food business, you need to deal with them right away. Some of the most common methods used to eradicate rodent infestations are:
Glue boards do not contain poison so you don't run the risk of contaminating food with chemicals. Rodents run onto the glue board and get stuck, though rats can often free themselves so they are more effective if you are dealing with mice. Be sure to check these often and discard of the boards and dead rodents once caught.
Mouse and rat traps are another option, with the spring trap being the most commonly used. Fresh food is used as bait, and the rodent is trapped by the spring when it tries to eat the food. Check traps frequently and dispose of dead rodents. (Wash your hands thoroughly afterwards!)
Poisonous baits should only ever be used with extreme caution and must be kept well away from food and food preparation areas. Employees should be instructed to stay well away from them.
Note: Extreme caution must be taken when using chemicals, such as poisonous baits, in a commercial kitchen. We recommended enlisting the services of a licensed Pest Control Operator to help you eradicate a rodent infestation in your restaurant or other food business.
